Replication Data for: Effects of forest management on mercury bioaccumulation and biomagnification along the river continuum
Negrazis, Lauren; Kidd, Karen A.; Erdozain, Maitane; Emilson, Erik; Mitchell, Carl; Gray, Michelle — 2022-07-15 This dataset contains the data used in the paper "Effects of forest management on mercury bioaccumulation and biomagnification along the river continuum." The dataset contains stable isotope data and total or methyl mercury concentrations collected on water, course particulate organic matter (CPOM), fine particulate organic matter (FPOM), seston, biofilm, invertebrates, and fish. These data were collected to study the effects of forest management on mercury bioaccumulation and biomagnification in food webs along a stream continuum.

Survey of metabolically essential trace metals in inland lakes and reservoirs across Canada: What constitutes a low metal system?
Borealis
Molot, Lewis A.; Schiff, Sherry; Baulch, Helen M.; Curry, R.Allen; Depew, David C.; Dove, Alice; Higgins, Scott N.; Kidd, Karen A.; Korosi, Jennifer B.; Paterson, Andrew M.; Pick, Frances R.; Venkiteswaran, Jason; Watson, Susan B.; Zastepa, Arthur — 2024-09-16 Trace metals are metabolically essential with many proteins dependent on metals for proper functioning yet little is known about the influence of low concentrations on freshwater microbial productivity and diversity. Dissolved iron (Fe), manganese (Mn), zinc (Zn), molybdenum (Mo), nickel (Ni), cobalt (Co), copper (Cu) and vanadium (V) were surveyed in 39 lakes and reservoirs across Canada representing different geology, dominant land uses, lake depth, trophic status and climatic zones. Concentrations varied considerably and cross-Canada patterns were not uniform among the eight metals, but PCA analysis revealed two major patterns: Co, Cu, Ni and V in one group and Fe and Mn in a second group. Sub-nanomolar concentrations of Co and Mo were common while sub-nanomolar concentrations of Zn, V and Ni were less common. Fe and Mn accumulated in the hypolimnion of the six lakes and reservoirs deep enough to thermally stratify with Co and Zn accumulation less common. Mo, Zn and Fe occasionally exceeded Canadian guidelines for protection of aquatic biota. Genomics and Monod growth kinetics were explored for their potential in identifying low metal environments and metal limitation without using metal enrichment bioassays. Metal concentrations in the cross-Canada survey were probably not low enough to limit growth but the impact of low metals on microbial diversity is unknown.

Replication Data for: Spatial patterns of microplastics in freshwater bivalves (Bivalvia: Unionidae and Sphaeriidae) relative to municipal wastewater effluent discharges.
Borealis
Kidd, Karen A.; Robson, Emily — 2024-10-25 This dataset accompanies a paper submitted to Environmental Toxicology and Chemistry titled "Spatial patterns of microplastics in freshwater bivalves (Bivalvia: Unionidae and Sphaeriidae) relative to municipal wastewater effluent discharges.". This study examined whether microparticle levels in resident mussels and fingernail clams and water samples were elevated downstream of wastewater treatment plant facilities in the communities of Hespeler, Ayr, and Caledonia along the Grand River, Ontario, Canada. All sampling for this work was done in August through September of 2021 and September of 2022. This dataset includes sample information for biotic and abiotic samples collected from the Grand River, a list of microparticles isolated from samples (including particle colour, morphology, and measurements), and information on chemical composition for a subset of particles.

Elements and omega-3 fatty acids in fishes along a large, dammed river
Borealis
Kidd, Karen A. — 2023-08-18 This dataset is used to support the paper submitted to Environmental Pollution titled "Elements and essential fatty acids in fishes along a large, dammed river". The dataset includes levels of Hg, 30 other trace elements, stable isotopes of carbon and nitrogen, and the fatty acids EPA and DHA in four fish species collected from four sites on the Wolastoq | Saint John River (New Brunswick, Canada) that were selected in relation to the Mactaquac Generating Station. It also includes physical characteristics of the fish including length, weight, age, sex and percent moisture.
